Depends:
Dandruff is flaking of the scalp. It can be simple shedding of skin. Can be due to sun burn. Can be due to infection, inflammation or other acute causes.

Dandruff is seborrhiec dermatitis in the scalp. This is due to an overgrowth of yeast named pityrosporum ovale. Some make sebum (oils) especially preferential for them to grow.
